Based on the information you provided (age 11, weight 103-106 pounds, 26-inch waist), it's difficult to determine if you're within a normal weight range without knowing your height. Also, a waist measurement isn't typically used to assess weight in children.
The best way to assess a healthy weight for a child is to calculate their Body Mass Index (BMI) percentile. This calculation uses your height and weight to determine a BMI score, which is then compared to other children of the same age and sex.
Here's what I recommend:
1. Measure Your Height: Ask a parent or guardian to help you accurately measure your height in inches or centimeters.
2. Use a BMI Calculator: Search online for a "BMI calculator for children." The CDC (Centers for Disease Control and Prevention) website has a reliable one. You'll need to enter your age, sex, height, and weight.
3. Understand the Results: The BMI calculator will give you a BMI percentile. The CDC defines weight categories based on these percentiles:
* Underweight: Less than the 5th percentile
* Healthy Weight: 5th percentile to less than the 85th percentile
* Overweight: 85th percentile to less than the 95th percentile
* Obese: 95th percentile or higher
4. Talk to a Doctor or Healthcare Provider: The best and most accurate way to determine if your weight is healthy is to talk to your doctor or another healthcare provider. They can consider your individual growth patterns, activity level, and overall health. They can also address any concerns you may have.
